County Climate Coalition

The County Climate Coalition is an effort lead by the County of Santa Clara that calls upon all counties in the U.S. to rally around combatting climate change. 


In June 2017, acting on a request by then Board President Dave Cortese, the Santa Clara County Board of Supervisors unanimously passed a resolution affirming the County’s commitment to the United Nations Paris Climate Agreement and establishing what has become the County Climate Coalition. This Coalition calls on all counties in the U.S. to rally around combatting climate change.

To move this vision forward, the County joined forces with Al Gore’s The Climate Reality Project to engage and encourage county governments across the United States to implement proactive strategies that reduce greenhouse gas and defend against climate change. The Climate Reality Project works in conjunction with the County of Santa Clara  to add members and supporters to the County Climate Coalition.

Consensus exists among the world’s leading climate scientists that we face a major global climate crisis caused by greenhouse gas emissions, with rising sea levels and melting ice sheets creating increasingly unpredictable and unhealthy living environments as we approach a dangerous threshold of global warming. Documented impacts of global warming include but are not limited to increased occurrences of extreme weather events, significant impacts to human health and safety, destruction of ecosystems, and reduced economic productivity. 

The United Nations Paris Climate Agreement (“Paris Agreement”) is a historic international agreement reached in 2015 aimed at reducing carbon emissions, slowing rising global temperatures, and helping countries deal with the effects of climate change. All but two countries in the world have signed the Paris Agreement, committing to enact programs to limit global temperature increase to less than two degrees Celsius above pre-industrial levels, with an expectation that this goal would be reduced to one and a half degrees in the future.

The United States ratified the Paris Agreement on September 3, 2016 and committed to its own target of reducing carbon emissions by 26 to 28 percent by 2025. On June 1, 2017, President Trump announced his intention to withdraw the United States from the Paris Agreement. The United States’ withdrawal could result in an additional three billion tons of carbon dioxide being released into the atmosphere each year, and an additional increase of as much as 0.3 degrees Celsius in global temperatures by end of the century.

States and local governments are leading the effort to combat climate change by reducing greenhouse gas emissions; reducing petroleum use in cars and trucks; increasing electricity derived from renewable sources; increasing the energy efficiency savings achieved at existing buildings and making heating fuels cleaner; reducing the release of methane, black carbon, and other short-lived climate pollutants; managing farm and rangelands, forests, and wetlands so they can store carbon; and periodically updating the state’s climate adaptation strategy.

[JURISDICTION]’s geographic location makes it particularly vulnerable to the devastating impacts of climate change, including rising sea levels, drought, flooding, and the concomitant adverse impacts on human health and the environment. 
Local jurisdictions, led by the County of Santa Clara, have resolved to take sharp exception to President Trump’s unilateral intention to withdraw from the Paris Agreement despite the dire consequences of the planet’s rising temperatures and opposition from communities across the country and world. Proactively responding to climate change provides opportunities to be at the forefront of innovation with respect to a broad range of technology, products, services, and know-how that transitioning to a climate-compatible future brings.
